Missing Michigan Family: Couple and 4-Month-Old Baby Disappear

Joseph Devenney/Getty Images(PETOSKEY, Mich.) -- Authorities and family members are searching for clues in the disappearance of a Michigan couple and their child.

Timothy Medsker, 33, and Sabrina Medsker, 34, vanished with their 4-month-old son Joshua without any warning. They were last seen at a birthday party for their niece and their last phone call was placed on Feb. 16.

The young couple has a successful cleaning business with strong ties to the small Michigan town of Petoskey. Despite attempts to track them down, the family and police haven't heard from them.

"This is 100 percent out of character and very concerning," said Kelly Manthei, Timothy Medsker's sister.

Police searched the home a second time this week and took computers and personal papers to look for clues about what happened to the family, but so far there have been no leads.

Nothing seemed out of the ordinary. The couple even talked about attending a baby shower this weekend.

"All of their personal belongings were there including clothing, computers, food, paperwork -- it looked like something spooked them," said Petoskey Detective David Schultz.

"Anytime we have a missing person or someone who can't be contacted usually in a small town like this a few phone calls and we know where there at, but obviously now almost going on three weeks this is not the case," said Schultz.

The family worries that there's something more to this story.

Police believe they left by choice and are likely traveling in their silver 2010 Ford F-150 pickup.﻿
